Re: Cryogenic Tempering of Wire

Hi all,

I have read most of the postings re why deep freezing can affect cable´s properties, and found a lot of extremely well built arguments about how that could change metallic structure of conductors. Most interesting, indeed!

But, going so deep, nobody has mentioned something more superficial (no pun), but maybe more easily relatable to the changes we are really interested at here: the non-metallic part of cables, ie the plastics, and the fact that metals change their phisical dimensions with temperature, and so do plastics, but at a quite different rate, so it´s unavoidable that the whole structure of the cable changes with such a dramatic change in temperature, simply due to changes in the spatial relationship between wire and insulating plastic, what will translate in differences in capacitance, maybe in inductance too. (After all, the only difference between Kimber VS and TC series is using PVC or Teflon as insulating/dielectric material, and sound is much better in TC)

Those were my two cents. Sure there´s more, please let´s know.

Best regards
